At present, the pit digger includes a gasoline engine, and a column with spiral blades is installed on the output end of the gasoline engine, wherein a grip is installed on the surface of the gasoline engine. After the personnel grasps the grip, the running gasoline engine drives the structure formed by the column and the spiral blade to rotate, which is convenient for digging pits on the ground. During the pit digging process, the distance between the legs of the personnel and the spiral blades is small, and the rotating spiral blades are easy to entangle the clothes on the legs of the personnel, which is less safe. Therefore, it is necessary to design a pit digging equipment with good safety. Utility Model Content

[0012] Beneficial effects of the utility model:

[0013] 1. Put the pipe sleeve on the column, and use the connecting screw to install the end of the L-shaped rod away from the pipe sleeve on the carrier plate to limit the relative position of the pipe sleeve and the column, and the pipe sleeve does not affect the rotation of the column. At this time, the pipe sleeve realizes secondary support for the column, reduces the load on the connection between the column and the output end of the gasoline engine, and improves the stability of the structure.

[0014] 2. Block rods are inserted into multiple through holes on the cross bar, so that the multiple block rods together form a shielding structure between the spiral blades and the legs of the person. When the structure formed by the spiral blades and the column rods digs a hole on the ground under the drive of the gasoline engine, the block rods are blocked by the ground and move upward along the through holes. Then, the block rods are always between the legs of the person and the spiral blades without affecting the downward movement of the structure formed by the spiral blades and the column rods, thereby preventing the spiral blades from entangled with the lower clothes and improving safety.

[0015] 3. When the connecting plate is installed on the carrier plate with the connecting screws, a gap is created between the connecting plate and the carrier plate under the action of the round table support. When the connecting screws cannot be removed by conventional means such as a wrench due to rust, insert a hacksaw blade between the carrier plate and the connecting plate and saw off the connecting screws to separate the L-shaped rod and the carrier plate, making it easier to separate the column rod from the gasoline engine.
